Application

Application Comment Organism
additional information exposure of PrtP, and not its proteolytic activity, is responsible for greater cell hydrophobicity and adhesion. The increased bacterial affinity to polar and apolar solvents indicates that exposure of PrtP on lactococcal cell surface can enhance the capacity to exchange attractive van der Waals interactions, and consequently increase their adhesion to different types of solid surfaces and solvents. PrtP or its derivatives may be used as a tool to construct strains with increased adhesion that form protective biofilms Lactococcus lactis subsp. cremoris MG1363

Protein Variants

Protein Variants Comment Organism
additional information strain PRTP- exhibits very low affinity for mono-polar solvents chloroform and ethyl acetate and apolar solvents hexadecane and decane (maximal affinity less than 20%), independently of their different physico-chemical properties (whether apolar, Lewis-acid or Lewis-base). Strain PRTP*, encoding anchored inactive PrtP, exhibits higher affinity to all solvents. More efficient adhesion of PRTP* strain to solid (glass and polytetrafluorethylene) surfaces as compared to PRTP+ strain Lactococcus lactis subsp. cremoris MG1363
